Almost 25 years ago, a fellow researcher in Belgium shared with me some information regarding my 6x great-grandfather, Jacques De Backer (1686-1764) who became a Bourgeoisie foraine by buying his citizenship in the town of Ronse. My correspondent told me that the source for this information was “familiearchief de backer” (De Backer Family Archive) records that were digitized by Herman Van Isterdael in 2001. I searched AGATHA for “familiearchief de backer” and damn me if I didn’t find it. Good news is there is a lot of stuff (I copied down the inventory of just the items in De Backer part of the archive. There are seven allied families and each of them has an inventory. The bad news is they will charge 0.64 euros per page.

He is the link to the archive: https://agatha.arch.be/en/data/ead/BE-A0514_115292_113984
Below is the De Backer inventory which I had translated from Flemish. I will have to go through this and pick out the items that are most interesting. There are 98 entries in the De Backer Inventory.
